My own homework
Pre-image
A(-6,8) Then I translate 7 units to the right and 1 up (in a 2x scale), that means (x+14),(y+2)
B(-10,4)
C(-6,4)
A'(8,10) Then I reflect this triangle in the x-axis, that means (x,y) > (x,-y) or -*y=-y
B'(4,6)
C'(8,6)
A''(8,-10) Then I rotate the triangle 90° clockwise, that means (x,-y) > (-y,-x) > (-x,-y)
B''(4,-6)
C''(8,-6)
A'''(-10,-8) Then I dilated the triangle 2.5, the equation is (2.5x, 2.5y) 2.5>0
B'''(-6,-4)
C'''(-6,-8)
F(-25,-20) And this is my final image.
G(-15,-10)
H(-15,-20)
